The Minoan eruption of Santorini was a large-magnitude natural event. However, in terms of scale it ranks smaller in erupted volume and eruptive intensity than the historical eruption of Tambora in 1815 AD, and smaller in sulphur emission and, by inference, climatic effects than both the Tambora and Mt. Pinatubo, 1991, eruptions.

The Semitendinosus muscle has an origin attachment point from the Ischial Tuberosity region of the pelvis as a tendon shared with the biceps femurs. and has an insertion attachment point on the upper shaft of the tibia.he origin attachment point of the Biceps Femoris muscle arises as two heads from the Ischial Tuberosity region of the pelvis as a tendon which is shares with the Semitendinous muscle.
